    Default Finder Bracket notch and Finder Mount tongue



    Newbie question. The bracket on my OTA for the finder scope has a notch in which a tongue on my finder mount mates. The bracket is mounted on my OTA with the notch facing toward the bottom (back?) of the OTA. This strikes me as that opposite of what I would expect. As is, if the locking screw on the bracket were to work loose my finder scope would slip out and hit my OTA. If the notch were facing the top (front?) of my OTA and the screw were to work loose this wouldn't happen since the tongue on my finder scope mount would still be trapped in the notch on the bracket.

    Am I missing something?

    That is the normal standard and it works fine.
    Just tighten the holding screw firmly and it will hold in place without issue.

    Thanks Gabby76. Curious though about the "why" for this standard. One would naturally tighten the holding screw but accidents do happen so it would seem to me that reversing the bracket would guard against such accidents.

    Just a repetitive design I imagine that has been the standard for decades.
    I have had a couple of heavier finders that had a shallow divot in the bracket foot for the bolt to fit into when attached.
    If your bracket is made of aluminium (not cast aluminium) you could do it yourself with a drill bit and put a 1mm divot for the bolt.

    What telescope do you have?
